A noted biologist,who had been studying little green frogs in a swamp,was stumped.The frog population,despite efforts at predator control,was declining at an alarming.A chemist at a nearby college came up with a solution:The frogs,due to a chemical change in the swamp water,simply couldn`t stay coupled long enough to reproduce successgully.The chemist the brewed up a new adhesive to assist the frog`s togetherness,which included one part sodiumIt seems the little green frogs needed some monosodium glue to mate.

Good try...But its not funny!
